14.58 acres of new wetlands were created for a net habitat
value gain of 9.23 wetland value points. This includes
10.13 acres of shallow water developments in upland sites,
4.1 acres of shallow water developments in low value
palustrine emergent (type 1,2,3 or 9) wetlands and the
creation of .35 acres of palustrine emergent wetlands
associated with shallow water developments.

36.64 acres of existing wetlands were eliminated for a net
loss of 16.57 wetland value points. This includes 4.1 acres
of low value palustrine emergent (types 1,2,3 or 9) wetlands
converted to shallow water areas and 32.54 acres of wetlands
converted to upland due to de-watering and replacement of
open ditches with buried pipelines.

There was a net loss of 22.06 acres of wetlands and a net

McElmo Creek EIS, wetland losses will be replaced on a v~h~'
basis.
